VEHICLE HUB AND AXLE.

Specification of Letters Patent.

Application filed March 30. 1912. Serial No. 687,492.

'1 0 all whom/1'7 may concern..-

Be it known that I, 'l lrnonoim (l. ()nnun, a citizen of the United States, residing at Anadarko, in the county of addo and State of Oklahoma, have invented new and useful Improvements in Vehicle llubs and A xles, of which the following is a speeiiicatitm.

This invention relates to vehicle hubs and axles, the object in view being to provide novel and e'tlective means for connecting a wheel hub to its axle in such manner as to positively exclude all dust, dirt, and Foreign matter, and prevent the esca 'ie oi? lubricant supplied to said axle spindle and skein.

A further object, incidental to the construction involved, is to strengthen the hub of the wheel, and materially increase the lite and durability thereoit'.

\Vith the above and other objects in view, the invention consists in the construction, combination and arrangement of parts, as will be hereinafter more fully described, illustrated in the accompanying drawings, and pointed out in the claim hereunto appended.

in the drawings: Figure 'l is a sectional view of a wheel hub, showing the adjacent end of an axle in proper relation thereto, and embodying the present invention. Fig. 2 is a detail view of the axle spindle and the union.

teierring to the drawings, 1 designates a wheel hub, 2 the spokes thereof, 3 the axle, and 4- the axle spindle.

in carrying out the present invention, I provide a hub, embracing an inclosing metal casing 5, as shown in Fig. 1, the said casing inclosing and covering the entire inner portion of the hub 1, and extending by preference beyond the plane of the spokes 2, said casing being provided with holes (3 which receive the spokes 2, When they are inserted into the hub, the spokes thus locking the metal casing 5 to the hub.

At the inner end, the casing is provided with a hollow cylindrical exteriorly threaded extension 7 which is adapted to receive an internally threaded union 8, mounted on the axle ii. The union 8 is Formed with a central hole 9 slightly larger than the axle Z-l, adapting the said union to be turned around the axle, and at the junction oi the spindle i with the main body oi t'h axle i"), the latter is provided with an annular flange it) lornn ing a shoulder. against which the union 8 bears, as clearly shown in the drawings. l u connection with the annular flange 10, a. washer ll oi leather or any suitable compressible material may be employed, the same being adapted to be conlined between the flange ill) and the end oi? the extension 7 to form a water and oil tight joint.

Extending into the center oi the hub '1 which is closed at its outer end, as shown, is an axle box 1), which is connected at its end to the extension 7. The inner end portion oi the box 12 is cyliinlrieal and tills the bore in the hollow cylindrical extension 7 of the hub casing, said box being driven tightly into the extension with a taper lit, as shown at i l.

1? designates a lock nut adapted, when the union 8 is in its final position, to bear against the end oi the union and prevent the same irom. working loose, thus securely locking the parts together.

From the i'oregoing description, it will be seen that by reason oi the outer end oi the hub being intact, it will positively exclude water, dust, dirt, and other Foreign matter, and by reason of the particular form oi con ncctio between the axle and the inner end of the hub, such i'oreign matter will also be excluded at that point. .l urthcrniore, the lubricating material for the axle spindle will be strictly eoniined within the hub, thus adding to the working qualities oi the device as a whole. l urthcrmore, the metal casing 5 serves as an e il'ective protection for the hub and prevents the drying out and cracking oi the vehicle hub.

What is claimed is:

A wheel hub, comprising a one piece n'letal hub embracing casing formed with spoke re ceiving holes which register with the spoke sockets in the hub, an externally threaded tubular extension at the inner end of said ing, and a lock nut on said extension bearing casing, an axle box having a cylindrical inagainst the union. ner end filling said extension and driven In testimony whereof I aflix my signature tightly into the same with a taper fit, an in presence of tWo Witnesses.
